For this case we have to:
- The payment per hour is $ 19.20
- The total payment was $ 1056
We can make the following rule of three to calculate the number of hours:
1 h --------------------> 19.20 $
x -----------------------> 1056 $
From here, we clear the value of x:
[tex]x = \frac {1056} {19.2}\\x = 55[/tex]
Answer:
I have to work 55 hours to earn a gross weekly pay of exactly $ 1056
